The tripping characteristic of the miniature circuit breakers must be selected to match the
loads to be protected and the maximum current provided by the supply unit in the event of a
short circuit.

Typical 24 V current consumption of the components

A separate 24 V power supply must be used for the SINAMICS S120 drive group.
The following table can be used to calculate the 24 V DC power supply. The values for
typical current consumption are used as a basis for configuration.
